Start and Idles fine stall when giving it gas.
Will idle drive, but as soon as I try to get to a normal speed it stalls.
No check engine light on.
I am thinking fuel filter or fuel pump.

This could be a fuel issue but it also could be a vacuum leak. So we need to check both.

here are guides that will show you how to do these tests:

Let's run through both of these and go from there. Let us know what you find. Thanks
